It totally depends where I found the 40 grand. If I found it in my home city, I would definitely turn it in, as I would feel guilty as hell if I kept it. However, if I was on vacation somewhere and I found 40 grand, I wouldn't really know what to do with it, so I would end up keeping it, or donating it to a non-profit org, like my fraternity for example, or something for breast cancer or something. I'm not sure. Maybe I'd keep it and pay for the rest of my schooling. I dunno, 40 grand is such a large sum of money.
